MLPAB-1570 - create a fault injection simulator template the ecs app

[andrewpearce-digital]

Purpose

Assess how the service will respond to faults using AWS Fault Injection Simulator

Fixes MLPAB-1570

Approach

• Create a role for Fault Injection Simulator to use
• Create an experiment template for ECS task faults
• deploy an SSM agent prerequisite in ECS task
• create these resources and deploy prerequisites when experiments are enabled

Note: This experiment doesn't have an automatic stop condition, but won't be run without team observation.
